Imported a spline-dxf from adobe illustrator. Converted the spline to polyline with explode command. Then no anchor points / vertex points / vertices were showing anymore. Simplified the polyline so that it had less than 1000 points. Vertices became visible.

I think some freeform objects need actually more than 1000 vertices. Also them need to be edited. Please increase the amount of vertices showing to biginteger
